Default Panasonic NP-VP33 Diode ID

I have a Panasonic NP-VP33 which is completely dead no lights nothing,upon opening this i noticed a diode which to my opinion has over heated.
Does any have a diagram for these so i can identify these components please

Many thanks

Ian

Looks like there could be a startup electrolytic to the left of the transformer, this is often the cause of no start of the psu.

Did you measure the voltages of the output?

You can sometimes get certain voltages on a dead set,though I do not think so if that 1uF is duff.
